IGMP Snooping

The DES-1252 uses IGMP Snooping to analyze data packets 
and  forward  them  through  only  where  appropriate.  This 
means  that  multicast  packets,  such  as  streaming  audio 
and video or other bandwidth hogs, get through without 
creating  extra  network  congestion.  This  smart  packet 
management also reduces the workload of other devices 
further down the line, making your entire network function 
more efficiently.

802.1x Authentication

The  DES-1252  utilizes  802.1x  Authentication  to  provide  a 
secure  means  to  allow  users  to  log  onto  your  network. 
When  used  in  conjunction  with  a  RADIUS  server,  802.1x 
requires each user to provide a username and password 
before accessing your network.

Smart Console Utility 

 

 

Inlcuded with all D-Link Web Smart Switches is an exclusive 
smart console utility that allows all D-Link Smart Switches to 
be discovered automatially with just a click of the button.

Operational Simplicity

The DES-1252 supports a wide array of plug-and-play features 
including: 

•  10/100Mbps auto-negotiation
•  Universal UTP cable recognition for auto straight-through 

or crossover cable detection

•  Full/Half duplex support
•  IEEE standards support

Managing  the  DES-1252  has  never  been  easier.  Using  its 
built- in browser-based management interface, configuration 
takes  only  minutes.  With  full  color  graphics  and  easy  to 
understand navigation menus, configuring the DES-1252 is as 
easy as surfing the Net.
